该网站的基本理念是 eBay 克隆。 针对这个问题，我正在尝试构建竞价网页。
错误截图:enter image description here
链接到没有nodes_modules文件夹的完整项目:enter link description here
我正在尝试创建一个变量，该变量将显示用户单击按钮后输入的出价。 我不确定是否需要创建一个包含出价数组的构造函数。
.ts 文件代码:
import {Component, OnInit} from 'angular2/core';
import {RouteConfig, ROUTER_DIRECTIVES} from 'angular2/router';
import {Hero} from './hero';
import {HeroService} from './hero.service';
@Component({
selector: 'BiddingPageComponent',
templateUrl: 'app/BiddingPage.component.html',
styleUrls: ['app/BiddingPage.component.css'],
providers: [HeroService],
directives: [ROUTER_DIRECTIVES]
})
export class BiddingPageComponent
{
var slot1 = 0;
myFunction()
{
slot1 = "{{slot1}}";
}
}
.html 文件中我需要更改的唯一部分:
出价时段 1:
<input type="number" name="fname" value={{slot1}}><br>
完整的.html文件代码:
<html>

最佳答案
因为您正在使用 Typescript，只需从 var slot1 = 0; 中删除 var
